ds needs breakfast. he needs to eat soon after getting up, he would kill someone before break time if he didn't eat. Doesn't really need lunch.
dd2 needs breakfast, you would notice if she didn't, but not like ds.
BUT dd1 (age 10) really doesn't do mornings. She is hard to wake up and hates eating when she has just got up. She needs to be awake for an hour before she can face food.
I wake her at 7 and she does have breakfast before she leaves, but not because she is hungry, only because I tell her too.
When she had pack lunch she ate something from her lunch at playtime, when she was then hungry. Now I send her in with a fruit snack for playtime.
When she goes to secondary she will need to be up and out of the house much faster, and I know already that she won't have breakfast. We have joked about it, but she will have a pain chocolate/fruit bar/banana to eat on the bus.
Some kids really can't eat when they first get up. Different people are different! If we know that adults are morning people or night owls, why is it so hard to believe that kids are too.
